COMP Cams 11/32" Positive‑Stop PTFE valve seal is part of a broad valve stem seal lineup that prevents oil from migrating into the combustion chamber via valve guide clearance. The positive‑stop PTFE style is used where extra spring clearance is needed, sitting between umbrella and O‑ring options in size and is intended for dual‑spring applications where sealing and space are both concerns.
